an operator loads the nozzle/de nozzle inner tube to the clamping device 120 at the product loading station a. After the detection unit detects that the product is loaded, the turntable 110 is started to rotate the product to the nut loading station B. The nut gripper 330 is driven by the first drive 340 to traverse and move up and down to transport the nut to the valve. The turntable 110 is activated to rotate the product to the nut lock down station C. The nut runner 410 is lowered into engagement with the nut and the rotor 412 is rotated to tighten the nut. The turntable 110 is activated to rotate the product to the valve core loading station D. The second guide portion 523 is lowered to the position of the valve mouth, and the valve cores are output one by one to the guide passage 521 by the valve core delivery device 510 so that the valve cores fall into the valve mouth. The turntable 110 is activated to rotate the product to the valve core adjustment station E (which is not the case if the product is a de-cud inner tube). The fourth driving member 620 drives the valve core rotating device 610 to descend to engage with the valve core, and the rotating member 612 drives the valve core to rotate, so that the two side wings of the valve core are pressed into the slots on the valve nozzle. The turntable 110 is activated to rotate the product to the cap pressing and feeding station F. The cap pressing clamping jaws 730 move transversely and vertically under the driving of the third driving piece 740, convey the pressing caps to the inflating valves, and drive the cap pressing clamping jaws 730 to rotate to tighten the pressing caps. The turntable 110 is activated to rotate the product to the inflation station G for inflation. After the inflation is complete, the turntable 110 is activated to rotate the product to the release station H.

Example 2

This embodiment provides an automatic de/english nozzle inner tube assembling device, which has a structure substantially the same as that of embodiment 1, except for the structure of the valve core feeding mechanism.

Referring to fig. 13, in the present embodiment, the valve core feeding mechanism includes a valve core delivery device 530 and a valve core guide 540, and the valve core guide 540 has a guide passage 501 for the valve core to fall vertically into the valve.

In one embodiment, the valve core delivery device 530 includes a valve core vibrating disk (not shown), a valve core straight rail 532 coupled to the outlet of the valve core vibrating disk, and a release 533. The valve core straight vibration rail 532 conveys the valve core in a vertical shape. The release member 533 includes a stopper 534 and a stopper driver 535 for driving the stopper 534 to move. The stopper 534 includes a first stopper 534a and a second stopper 534b that are spaced apart from each other in the front-rear direction and are offset from each other in the left-right direction. In the closed position, the first stop 534a stops between the leading valve core and the guide channel 501 to prevent the valve core from entering the guide channel 501. In the release position, the second stop 534b stops between the next valve core and the guide channel 501, allowing the first valve core to enter the guide channel 501 and blocking the next valve core from entering the guide channel 501. The stop driver 535 drives the stop block 534 to reciprocate between the release position and the closed position to release the valve cores one by one. The stop actuator 535 is embodied as a pneumatic cylinder. The first stopper 534a extends in the driving direction of the cylinder, and the second stopper 534b is connected to the output end of the cylinder through a bent member.

The valve core guide 540 includes a first guide shaft 541, a second guide shaft 542, and a slidable drive member 543. One end of the first guide shaft 541 is configured with a side notch into which the valve core enters, and the other end is configured with a sliding portion, and the second guide shaft 542 is sleeved on the sliding portion and is slidably connected with the sliding portion. The slidable driving member 543 drives the second guide shaft 542 to slide up and down with respect to the first guide shaft 541. Specifically, the first guide shaft 541 is fixed and positioned at the discharge position of the valve core conveying device 530 by a fixing means such as a fixing plate, and the upper end of the second guide shaft 542 is sleeved outside the sliding portion, and is driven by the sliding driving member 543 to slide along the sliding portion. The sliding driving member 543 is specifically a cylinder. Preferably, the outer diameter of the sliding portion is smaller than the outer diameter of the first guide shaft 541, and the outer diameters of the first guide shaft 541 and the second guide shaft 542 are substantially equal, so that a limiting surface is formed at the joint of the sliding portion and the first guide shaft 541, the second guide shaft 542 is limited from excessively moving upwards, and the appearance of the product is attractive and elegant.

The hollow shaft holes of the first guide shaft 541 and the second guide shaft 542 constitute the guide passage 501. The inner diameter of the shaft hole at the lower end of the second guide shaft 542 is greater than or equal to the outer diameter of the valve, so that the valve can be sleeved in the bottom of the second guide shaft 542. Preferably, the outer diameter of the valve is substantially matched to the inner diameter of the second guide shaft 542 to ensure that the valve core falls vertically into the internal cavity of the valve.

When the product reaches the valve core feeding station, the sliding driving piece 543 drives the second guiding shaft 542 to move downwards to be sleeved in the valve, and then the valve cores are conveyed to the guiding channel 501 one by one through the valve core conveying device 530. The valve core enters the cavity of the valve through the guide channel 501.

The foregoing description of certain preferred embodiments of the utility model has been presented with reference to the drawings. It should be understood by those of ordinary skill in the art that the specific constructions and processes illustrated in the foregoing detailed description are exemplary only, and are not limiting. Furthermore, the various features shown above can be combined in various possible ways to form new solutions, or other modifications, by a person skilled in the art, all falling within the scope of the present invention.
